Need help for my cousin!

Hi everyone I'm not really sure if this is the right place to post however I'm going to try, anyway, my cousin has a 6 year old disabled daughter she is incredibly attached to her special blankie of which she has two, both are now starting to show signs of having seen better days, these blanked have been through so much with her including multiple operations during her first few years of life and as you can imagine they are a great source of comfort to her, we are having trouble getting our hands on replacements so any help would be super appeciacted, thank you all so much in advance! 😊
